Summary

Nefesh B'Nefesh

Israel · AI-generated

nonprofit aliyah israel small

The AS handle NEFESH is held by Nefesh B'Nefesh, a nonprofit organization dedicated to facilitating Jewish immigration (aliyah) to Israel.

What it's used for

  • The address space carries the organization's internal network infrastructure, as indicated by the netname Nefesh and registrant Nefesh B'Nefesh Aliyah (R.A.).
  • The inventory consists of a single IPv4 prefix, 91.220.22.0/24, comprising 256 addresses, with no IPv6 prefixes announced.
  • With only 1 observed neighbour, the network operates as a small, isolated endpoint rather than a transit or access provider, consistent with the needs of a single-site nonprofit organization.

Notable

  • The RDAP registrant Nefesh B'Nefesh Aliyah (R.A.) aligns directly with the AS holder and the announced prefix netname.
  • The address inventory is minimal, consisting of a single /24 block, which reflects the limited scale of the organization's technical footprint.

Classification and threat

Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.

Spamhaus DROP

Not on ASN-DROP The network as a whole is not listed.

No DROP prefixes None of its announced space is on the DROP prefix list.

Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 446 networks and 1,852 prefixes, as published 2026-10-27. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.

FBI IC3

No IC3 indicators Nothing from the FBI IC3 feed.

IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
